Try to to use proxy_pass with the local host and without quotes.

Say you want the application on port 3001 as your website, you need to configure it like that:

location / {
    proxy_pass http://localhost:3001/;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
}

This code needs to be in the server block of your default file.

It will pass all traffic from the location / (your web root) to the port 3001.

A complete example would look like this:

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    server_name example.com;

    location / {
        proxy_pass http://localhost:3001/;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

Explanation:

proxy_pass http://localhost:3001/;

This will pass all traffic to the port 3001.

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

This will pass informations such as the IP which made the call to the proxied server.

proxy_set_header X-Forwarded-Proto $scheme;

This will forward the used sheme/protocol information of the request.

Mostly your configuration file problem. see, below example different express apps running in 3000 and 3001 ports. this is how the config file looks like in my nginx config file

server {  
    listen 0.0.0.0:80;
    server_name stage.chat.in www.stage.chat.in;
    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $proxy_host;
        proxy_set_header X-NginX-Proxy true;
        proxy_pass  http://127.0.0.1:3000;
    }
}
server {  
    listen 0.0.0.0:80;
    server_name api.chat.in www.api.chat.in;
    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $proxy_host;
        proxy_set_header X-NginX-Proxy true;
        proxy_pass  http://127.0.0.1:3002;
    }
}
